A drawer support having the characteristics of my present invention, as before outlined, is particularly usefuhand applicable to drawer cabinets such asare used for instance in the vertical system of filing papers wherein the contents of the drawer are often indexed to the extreme rear wall thereof and must therefore be readily accessible for both inspection and for removal in a vertical direction and I have therefore illustrated the invention in its present embodiment in connection with such a cabinet comprising a main supporting structure 1, hereinafter termed the casing, the same being in the present instance of a skeleton type to form one or more drawer chambers, only one of which is herein shown in its entirety. Operating in this drawer chamber is a drawer having a front wall 2 that normally closes the front of the chamber, side walls 3 and a bottom all 4, the width of the drawer in rear of its front wall being slightly less than that of the chamber at the same point so that there may be accommodated between each wall of the latter and a wall of the drawer, a supporting mechanism as hereafter referred to. As this supporting mechanism is duplicated upon the two sides of the drawer in the present instance to properly distribute the weight, the following description will be in the singular and con fined to an explanation of one such group, the other being identical with the exception of the differences of right and left hand parts.

Referring first more particularly to Figs. 3, 7 and 8 an extension support 5 is interposed hctwecn the drawer and casing that is provided with oppositely turned upper and lower Ways 6 and 7 to receive res ectively the supporting and guidin mem ers on the drawer and casing. I pre er to form this support of a single piece of sheet mate rial bent somewhat in the form of an S, as shown, in which manner are derived upper and lower flanges 8 and 9 forming respec tively an upper track on the upper way and a lower track on the lower way and an in termediate web 10 forming the lower track of the upper-way and the upper track of the lower way. Arranged to-travel in the up per way 6 is a carrier 11 in the present form of a channel bar having its open side upper-most and journaled at to ard and rearward positions thereon are two rollers 12 and 13, respectively, which bear upon the lower track 10 of the way, while an extension at the rear end of the carrier has journaled therein an upper roller 14 held in a position to engage t e. upper track 8 but normally spaced slightly therefrom. The carrier is held against the closed side or lateral wall of the way by a projection 15 thereon that extends downwardly into the channel of the carrier and prevents lateral disengagement thereof from the way although it is free to move longitudinally therein, its rearward movement being limited by a stop 16 engaged by the rear roller 13 and its forward movement by a stop 17 engaged by the forward roller 12.

A horizontally projecting supporting flange and guide 18 having an attaching portion 19 is secured to the side wall 3 of the drawer and projects into the upper way 6 of the extension support 5 between the tracks 8 and 10 thereof and rests upon the rollers 12 and 1.3 of the carrier 11 and be tween the lower rear roller 13 and the upper roller 14- of the latter, which rollers cooperate respectively with the upper and lower guiding faces of the flange, while a second upwardly extending flange 20 at the outer edge of the first engages laterally of the upper roller 14 and prevents lateral disengagement of the drawer from the carrier. This guiding flange is also engaged for the same purpose directly by an off-set projection 21 on the lateral wall of the we 6.

supporting and guiding flange 22, shown in Fig. 10 is secured b an attaching portion 23 to the casing 1 an carries on its upper side a projection 24 that cooperates with the channel of a second inverted channel bar carrier 25, shown in detail in Fig. 11, to hold the latter on the guide. This carrier is substantially the same as the carrier 11, but is in an inverted position, the forward and rearward rollers 26 and 27 being arranged to cooperate with the upper guiding face of the tange 22 and the single rearwaid roller 28 with the under face, the

latter being normally slightlyspaeed therefrom. This flange 22 with its carrier 25 is received within the lower way 6 ofthe extension support in a similar manner to the flange of the drawer in its way so that it is between the upper and lower tracks 20 and 9 of the way upon which tracks respiwztively engage the rollers 26 and 27 of the carrier. An upwardly projecting off-set flange 29 on the attaching portion 23 carried by the easing coiiperates with a projection 30 on the rear end of the extension slide and tends to prevent relative lateral disengagement of the way 6 and the supporting guidc fif when the drawer is withdrawn, the front end of the extension support being always prevented from disengaging in the direction of the drawer as it is constantly in engagement therewith, as will hereinafter appear, while the rear end of the support is not.

It will thus be seen that the carrier 25 is supported on the guiding flange 22; that the extension support 5 travels on the carrier 25; that the carrier 11 travels on the upper way of the extension, support 5 and that the supporting flange or guide 18 of the drawer is supported and travels on the carricrili. It will also be observed that while the rollers on the two carriers act between the latter on the one hand and the tracks of the ways and the faces of the guiding flanges on the other, in the sense that they are journaled on one part and bear on the others, it is also true that the rollers act directly between the guiding faces of the flanges and the tracks of the ways in which view the earriers 11 and 25 act in the capacity of spacing members to keep the rollers in their proper relative positions. arate sn allcr rollers might be used in the proportion of two to one of each large roller, as shown in Fig. 12, in which the rollers a bear upon the lo ks of the ways 6 and 7, while the rollers Rhear upon the guiding flange of the drawer o casing.

As to the operation of the device, a for-- wardly arranged stop or abutment 31. on the top of the extension support 5 is provided out of alinement with and preferably below a stop or abutment 32 provided in a roarward position on the side wall 3 of the drawer, but as the drawer is drawn cut from the position of Fig. 1 a latch bar 33 pivoted at 34 to the drawer simultaneously engages these abutments or is, in fact, in the present instance, in normal engagement with the abutment 32 and in a position to engage the abutment 31 and the drawer and extension support are thereby interlocked at a predetermined point in their relative movement. During its initial movement, the drawer first travels on the carrier 11 and the rollers 12 and 13 thereof until the first mentioned roller reaches its limit of forward movement by engaging the stop 17 In either instance, sep-' the drawer and extension support while the drawer is in a partially extended position. Continued outward pull on thedrawer causes the extension support to travel in a similar manner on the carrier 25 and on the rollers 26-and 2Tthereof until the latter, in its .torward nnovement on the guide 22 on, the casing, engages with the projection 24 -whereat it is halted. As it halts, it is engaged from the rear by a stop or abutment 35 at therear of the lower way? of the extension'support so that the latter is, through the inediumof the carrier, locked with the guide on the casing and vprevented from being Withdrawn too far. hen this action has occurred the drawer is in its fully extended position, as shown in Figs. 2 and-6.

Assuming the drawer to be evenly loaded, its weight will be approximately evenly distributed when it is in its closed position on the carrier 11 and the lower rollers 12 and 13 thereof and it will still rest thereon until its .center of gravity passes over the forwardly arranged roller. The guide 18 of the drawer will then leave the rear roller 13 and engage the upper roller M with its opposite face which roller will be raised slightly to bear upon the upper track- 8 of the upper way on the extension support and prevent relative tilting of the parts. The same action occurs with respect to the lower carrier 25 acting between the extension support and the guide on the casing except that the arrangement of the rollers on this carrier being reversed the initial travel will be on the upper rollers 26 and 27 and the bean ing will then be transferred from the roller 27 to the lower "roller 28 enga ing on the under guiding face of the gui e 22 of the support. By inspecting Fig. 6, it will be seen why the projection 30 on the extension support 5 is arranged at the rear end of the latter to engage the retaining flange 29 and prevent disengagement of the support from the guide in an inward direction.

When it is desired, for any purpose, to entirely remove the drawer from the casing, the operator has simply to rotate the latch 33 thereon from the full line position of the figures to the dotted line position shown in Fig. 2 wherein its engaging portion rests in rear of the abutment 32 on the drawer. The abutment 31 on the extension support 5, be ing, as before described, out of alinement with this abutment 32 on the drawer, the latter readily clears it and issues from the front end the upper way 6 of the support above the stop 17. For the re-insertion of the drawer the latch is restored to its former position and the rear end of the retaining flanges 20 of the drawer guides are threaded behind their cooperating projections 21 on the ways which, it will be noted, are readily accessible for this purpose. The operator has then only to thrust the drawer inward in the ordinary manner whereat the latch 33 will ride the abutment 31 as it passes the same and fall in behind it to its norma position in engagement with the abutment 32.
